This invention relates tol deck plates and the object of the inventionis to provide a deck late which ma be used in the constructlon of roofs,dec s, floors and the like.

6 Another object of the invention is to provide a means for securing thedeck plates to v the supporting beams on which the deck plates aresupported and to provide a means arranged to hold the adjacent deckplates in 10 position4 with the surfaces extending at the same level.

Another object of the invention is to provide a means for firmlysecuring the deck plates to the supporting beams with a minimum of timeand labor.

A further object of the invention is to provide a deck plate which maybe utilized for building u roofs, decksjr floors in sections.

These o jects and theseveral novel features of the invention arehereinafter more fully described and claimed and the preferred form ofconstructibn by which these objects are attained is shown 1n theaccompanying drawings in which- ,Fig 1 is a perspective view of a deckplate embodying my invention.

Fig. 15 is a view showing an alternative form of clip. l

The deck plate is shown in Fig. 1 and vis formed from sheet metal havinga depending return bent flange 1 at one edge anda depending flange 2 atthe opposite edge. Intermediate the edges this deck plate is providedwith a depressed rib 3 equal in depth to the flanges 1 and 2 providing aspace 4 therein and the returnbent flange 1 provides a space 5 along theedge ofthe deck plate. These deck plates are assembled as shown in Fig.2 with the ange 2 of one deck plate engaging in the space 5 of the nextadjacent deck plate and these deck plates are alsoassembled in alignmentendwise and inter-engage as will be understood more particularl fromFig. 8. In order to secure the dec plates to the supporting beam 10 aclip 6 is provided, shown 1n Fig. 3, having a` depending flange 7adapted to be inserted in the space 5 in the return bent ed e 1 of thedeck plate and having a depen ing portion 8 which, as shown in Fig. 3,is provided with a notch 9 for the flange of the channel beam 10. Thisclip isv inserted in the edge of the `deck plate 'as'shown and aslit ismovable longitudinal-ly of the deck plate it may be driven onto theflange .of the channel beam with a hammer to firmly secure the deckplate thereto. This clip is shown in perspective in Fig. 5 and isprovided with an outwardly turned lug 30 which may be bent down to theposition shown in dotted lines Iin Fig. 4 after the clip has been drivenonto the channel 'beam to engage behind the channelv beam and thusprevent movement of the clip in either direction. The flange' 2 of thenext adjacent 1 deck plate is\then inserted inthe space 5 as Shown atthe right of Fig. 3 and engages over the clip as shown. f

In order to hold the 'adj acent deck plates inclip is bent around thereturn bent flange as shown in Fig. 6. -lfhe depending flange 2 of thenext adjacent deck plate is then inserted in the channel 13 in the clipand the end 14 of jthe'clip is then bent over the ad'acent deck'plate asshown in Fig. 6. By t is arrangement the deck plates are securedtogether and the adjacent edges of. the deck plates are held at a commonlevel and are prevented from moving up or down in relation to eachother.The deck lates are built up in this manner and the anges 1 and 2together with the depending ribs 3 provide girders which strengthen thedeck' plates to withstand pressure. As the deck plates overlap endwiseexpansion or contraction lon itudinally is readily absorbed and byproviding the longitudinal spaces 4 in the central ribs of the deckplates lateral expansion` or contraction is readily absorbed. When thedeck plates are used in this manner to provide a fiat roof asshown in Fi2, la ers of insulating material, such as as estos oard or the like, maybe laid thereon and covered with weatherproongmaterial such as tar and afinal laye;` ofgravel may be used to complete the rooi'ln surface.

When t e deck plates are to be secured to I beams instead of channel'beams as hereinbefore described a different form of-clip is providedwhich is. shown in Fig. .9. In this formthe clip is provided with a deending ange. 15 adapted to be inserted in t e space 5 in the return bentedge l of the deck plate and this clip is provided with a portion 16 ibent at-a right angle to the body of the clip.

and having ends adapted to be bent under the edges of the I beam asshown. This prevents movement of the clip in leither direction in thespace 5 and the flange 15 may be covered by the depending flange 2 ofthe next adjacent deck plate in the same manner as is shown at the rightof Fig. 3.

The deck plates may be reversed in ositi'on as shown in Fig. 10 toprovide a ribbed roofing. In this casethe deck plates fit together inthe same manner as' shown in Fig. 2 but are reversed so that the ribsand flanges extend from theupper side of the deck plates. In this formof roof the' fianges of the deck plates extendupwardly and fit' togetherin a manner to prevent leakage and it is necessary to secure these deckplates to the purlins ings through the deck plates through which fleakage could occur. For this pur ose when the roof is sup orted onchannel earns the clip 6 shown in igs. 4 and 5 is used with theexception that in this case the flange 7 engages over the flange 2 ofone of the deck lates, as shown in Fig. 11, and the return ent flange 1of the next adjacent deck late engages over the ange -7 of the clip 6.lipsl 11 are also used as shown in Fig. 10 to secure the deck platestogether and of course, the clips are reversed in position due to thereversing of the deck plates. If the supporting beams for this type ofrooing are I beams the clip shown in Fig. 9 is utilized for securing thedeck plates to the I beams and are interengaged with the deck Fig. 13.

. These deck plates may also be used in the reverse position forbuilding up a floor or a flat deck as Awill be understood from Fig. 12.In this case the deck plates are laid on the supportingI beams With theribs and flanges extending upwardly as shown and the clip shown in Fig.9 is used to secure the deck plates to the I beams as shown' in Fig. 13.In this case the flange 15 of the clip `engages over the iange 2 of onedeck plate and the return bent flange l of the next adjacent deck platefits over the clip as shown and the ends of the clip are bent over theedges of the 1 plates as shown in beam to secureA the j deck platesthereto. Be-v tween thebeamsclips 11 are used as shown in Fi 10 tosecure the deck plates together and hod them at the same level and theconcrete is poured over the ribs and flanges of the deck plates as shownin Fig. 12. The ribs and flanges provide strength and combine with theconcrete to form reinforcements and in order to firmly anchor the deckplates in the concrete the intermediate ribs 3 of the deck plate may beapertured and'tapered pins 20 may be driven through these apertures asshown in Figs. l2 and 14. When the concrete is poured these pins areembedded inthe concrete and prevent any possibility of the ribs freeingthemselves in the concrete after the concrete has set. Reinforcing barsmay be laid between .and over the ribs of the deck plates if desired tostrengthen the concrete floor when lplonsiderable welght is to besupported by the oor.

This arrangement allows a fioor or deck-to be laid without providingmold boards for the under side of the floor. and without using jacks tohold the mold boards in place.

This provides a floor of low cost and the ribs reinforce the concretebetween. the supporting beams and combine with the concrete to "25 looland may Ve provided with deeper ribs and anges to increase the strengthlof the deck plates as will be readily understood'. Asxthe iso f Lacanau'deck plates may overlap, at the ends to an extent desired deck plates ofthe same len may be used in a building in which the spacing of the beamsfor supporting the eck plates varies to considera e extent.

The channel beam clip shown in Fig. 5 ma be made reversible by slittingthe fian e to provide end portions 32 which may be ent over onto theopposite side. of the clip as 1 shown in Fig. 15. This clip is used whenthe deck plates are arranged as shownin Fig. 3, and the lugs 32 may beengaged over the return bent lange 1 of the deck plate when the upperedge of the supporting.. channel beam extends in one direction while byreversing the clip the flan e 33 ma be engaged over the return bent edge1 of t e deck plate when the edge of the channel beam extends in theopposite direction as will be understood from Figs. 3 and 15. Thisrovides a clip which is reversible to engage t e channel beam flange'from either side and may be driven onto the flange to firmly secure thedeck plates thereto. From the foregoing descriptlon it becomes evidentthat the device is veryv simple and eficient in operation, may be usedin several diierent ways, is of low manufacturing cost and provides adevice which accomplishes the ob'ects described. so aving-thus fullydescribed my invention, its utility and mode of o eratlon, what I claimand desire to secure y Letters Patent of the United States is l -A clipfor locking the anges of deck lates in inter-engaged relation to'.prevent re ative movement of such deck plates at joints lying betweenand unsup orted by supporting joists or purlins, sai clip bein formed insubstantial S shape of a sin le piece of mate- I '40v rial andcomprising top and ttom members connected by an intermediate member,said top and bottom members lying onI op osite si es of and beingsubstantie y para el to said'intermediate member, said top member havingan extension lying in Lthesame plane therewith and projecting beyond oneend of said intermediate member, andsaid bottom member havingan-extension lying'in the same plane therewith and projecting beyond :sothe opposite end of said intermediate member, said extensions beingadapted to be bent over the flanges of said deck lplates in -theassembly thereof. 'i

In testimony whereof I sign' this specifics lss/tion.
